A (2,1)
B (1,3)
C (5,5)
Suppose a rectangle ABCD has the coordinates shown.
Find the coordinates of point D.

Answer: (6,3)Step-by-step explanation:The midpoint of AC and BD are the same because a rectangle's diagonals cut each other in half. D = A + C - BD = 2 + 5 - 1 = 6D = 1 + 5 - 3 = 3 D = (6, 3)

I think your answer would be (6,3)
